8 Claims, (Cl. 229-458) This invention relates to new and useful improvements in paper bags, and, more particularly, the aim of ,the invention is to provide a .novel and valuable bag made of ordinary paper bag sheet material, wellknown to be relatively weak, but incorporating two permanently carried comparatively small sheet additions of cardboard or o f some other material of Asuitably greater heayiness and strength than said ordinary paper bag Asheet material; such `parts combined pursuant to a con.- cept involving special ,inexpensive formations includins openings through said additions and matching `openings :through the two walls of the bag. A bag is thereby provided of high utility in various fields, as, A,for instance, when used as a housewifes shopping .bag

By the provisions of the present invention, the new bag, which may .have one of its two walls extended higher than the other such wall, can be securely locked Closed at its top and at the locations of said additions, and then a hand opening is .provided Inear the top of the bag fortified by said additions in AVsuch manner that, with the bottom and sides .of said opening marginally attended by .a .large Kplurality of plies of .Sheet 4material, the top 4stretch `of said opening, acting as the bas handle. not .only :includes a plurality 0I plies of said ordinary :bag sheet material but also is fortified by a number of plies 4of both said tad.- ditions.

The Varrangement is further such that not only is great strength provided all around said lopening, but `said top stretch thereof is of such overall thickness as -to establish a most comfortable handle; the same `including Athree plies lof the sheet material `of which said additions are made, as well `as an equal number of plies of the ordinary bag sheet material.

At the same time, for maintaining the parts as just described once the bag is closed at its top, a tongue and slit means is carried by the two additions .and so arranged that by simple downward insertion of the tongue into its slit such maintenance can be assured.

For further comprehension of the invention,

and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features ,of the invention are more particularly vset forth.

In `the accompanying drawings forming 1a material part of this disclosure:

Fig. 1 illustrates a now favored embodimentof the invention, and :one in which .one vbag wall extends higher than 'the other; this view, where.-

2 in the longer wall is the far one, showing said longer bag wall not yet turned down over the shorter wall along a line of fold paralleling the top of the yshorter wall.

Fig. 2 is a view similar to Fig. l, after the upper portion of the longer wall has been folded down over the shorter wall and the top of the bag locked closed to provide the hand opening and handle aforesaid.

Fig. 3 is an enlarged fragmentary vertical section, taken on the line v3 3 of Fig. 1.

Fig. 4 is a similar View, taken on the line 4 4 of Fig. `2.

Fig. l.5 -is a partially sectional fragmentary elevation, on the same scale as Figs. 1 and 2, of the upper central portion of the longer bag wall as the latter would ybe viewed from the line 5 5 of Fig. v3.

Referring to the drawings more in detail, the bag, generally marked sl, is mede in any of the usual ways in the art of paper bag manufacture to include a pair of walls vIl and I2; the wall I2 being here shown as the longer one so as to in- Corporate a top extension I4, below called the top flap. Said top flap centrally thereof has an up.- wardly projected portion I5 upwardly extended from which is a tongue I5.

'The two fortifying 4additions above-mentioned are marked respectively I5 and Il- The addition I6 is suitably secured, as by a-n adhesive, to the inside of the bag wall l2, at a location relative to the latter as shown. This addition is lsubstantially square, with a tongue I8 projected at its top center, said tongue I8 for matching the tongue I5 on the bag wall l2. The addition I Ii has an upper larger `horizontally elon gate opening i9, and a lower similarly elongate opening 20 of the same length as the opening lI9 but of less width and preferably about half as wide.

These vopenings are s o .placed lon the addition L6, and the V upwardly projected portion l5 from the top flap I4 is so located on the latter, and said top flap is so `apertured at two ypoints that with the addition I6 secured to the bag wall l2 in correct position thereon, said portion I5 registers with the upper half of the addition IfS, such apertures match the openings I9 and 26 of the addition 1,6, and the entirety of an area of the bag wall I2 corresponding lto the area of the said addition I 6 is of two-plythickness.

Then also the bottom of the opening I9 is aligned with the top .of the bach wall l2. Thus when said top .Hap t4 is folded `down as in Fig. 2, such ,fold traverses the `addition -I 6 by crossing .the

3 two sides thereof which mark the bottom of the opening I9.

The addition I'I is suitably secured, as by an adhesive, to the inside of the bag wall Il. As made plain in Fig. 1, the addition I'I is of the same width as the addition I6; and is almost of square outline. The addition I1, aligned with the addition I6 laterally of the bag top, has its upper edge at the top of the bag wall II, so that, as most clearly shown in Figs. 3 and 4, the bottom of the addition I6 is above the bottom of the addition I'I.

The addition II is provided with a potential horizontally elongate opening 2|; this opening being termed potential because, with the addition II cut, as it is, only along the two ends and one only of the sides of such opening, there is primarily provided a flap 22, and thus, only when said flap is arranged as in Figs. 2 and 4, is the opening 2| actually produced. Then the opening 2|, together with the matching half of the opening I9 of the addition I6 when the parts are arranged as in Figs. 2 and 4, participates in the establishment of the hand opening at which the bag is grasped for carrying the same.

The cutting of the addition I1 to produce the nap 22 is such, as will be noted, that when said iiap is swung out, the said hand opening is of the same length as the openings I9 and 20 of the addition I6 and of the same width as the latter and so only half the width of the former.

Also, the horizontally elongate portion of the addition I'I topping the nap 22 is of the saine width as said nap, to predetermine that when the parts are arranged as in Fig. 2 the opening 2| of the addition I1 will register with the opening 2D and with the then lower half of the opening I9 of the addition I6; the just referred to half of the opening I9 being of course the upper half thereof in Fig. 1.

Thus, as previously pointed out, the said hand opening by which the bag is manually carried is participated in by half of the opening 20, and also by the opening I9, and further by the opening 2| when established by redisposition of the flap 22 as in Figs. 2 and 4.

The addition I'I is also provided with a slit 23; and the bag wall I I carrying said addition is cut so as to have a ap and a slit respectively matching the flap 22 and the slit 23. As already stated, the bag wall I2 carrying the addition I6 is apertured at two places so that such apertures match the openings I9 and 20 of said addition.

As clearly shown in Fig. 3, with the partenarranged as shown there and in Fig. 1, the bag has an open mouth extending all across the width of the bag. To arrange the bag as in Figs. 2 and 4, all that is required is to fold down the top flap I4 and with it the addition I6 to dispose said flap and something more than one half of said addition over the upper portion of the outer side of the bag wall II, insert the tongue IB through the slit 23, and fold out and upward the ap 22.

Then, as shown in Fig. 4, the hand opening by which the bag is manually carried is participated in, as already said, by the openings I9, 2U and 2 I as well also as by the matching openings through the bag walls I I and I2, the load-sustaining ends of said hand opening are inclusive of three plies of the strong material of which the additions I6 and I'I are made, and the top stretch of said hand opening, this acting as a bridge-type handle, is inclusive of the same plies as present at said loadsustaining ends; while, further, to give a most comfortable hand-grip, said handle includes in its lateral bulk the thickness of the flap 22 plus an additional ply which is a portion of the bag wall II.

The fabrication of the new bag is easy and inexpensive, and the production of the additions I6 and II is likewise of triing cost, in which latter connection it is to be noted that there is negligible waste of material in making said additions. Y

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
